Abstract (en)
[origin: EP2230459A1] A combustor 3 of a gas turbine includes an inner premixed gas generator 33 and an outer premixed gas generator 34 that produce combustion flame, an inner cylinder 31 that has therein the inner and outer premixed gas generating units 33 and 34, and a transition piece 32 that connects the inner cylinder 31 to an inlet of a turbine. The outer premixed gas generator 34 is placed surrounding an outer circumference of the inner premixed gas generator 33. The inner premixed gas generator 33 and the outer premixed gas generator 34 are placed with a cylindrical swirler ring 35 interposed therebetween. In the combustor 3, a part of each inner wall surface of premixed gas generator outlets 333 and 334 of the premixed gas generators 33 and 34, which is located outward in a radial direction of the combustor 3, is extended further in an axial direction of the combustion flame than a part of the inner wall surface, which is located inward in the radial direction of the combustor 3.
